2012 Wagon boot lock releases ramdomly, closing doors or hitting bumps

[Anth76]

I have a 2012 Elegance wagon, and am having issues with the boot lock.



I bought it 2nd hand August last year. A few months later, my wife mentioned the open door indicator on the dash would flash up randomly, and when you get out & pull up on the boot (not using the boot release button), the boot will open up.


At least 50% of the time, when you close the boot normally, you hear (what I assume is) the electronic lock solinoid whir in and out, like its tried to secure the lock in place, then releases immediately after. You can then pull the boot up without using the release button.


As well as randomly opening, it often happens when you roll over a speed bump, or when the car is stationary & turned off, and you shut one of the other doors firmly.


Usually if you slam the boot down, it will stay in place, but it might take 2 or 3 slams, and its not guaranteed it will stay properly closed for the duration of the trip.


The only way we've found to prevent the random opening, is to slam it & immediately press the central locking, which disables the solinoid I assume.


But to make matters worse, in the last week or so, my wife has been unable to open the boot at all, using the release button or the key fob. She's tried starting & turning off the car, continually pressing the button, etc, then maybe 2-5 minutes later it will open when pressing buttons etc.


A Skoda workshop have replaced the lock mechanism, and now the release button mechanism, but the problem continues (in fact the new issue of being able to unlock the boot has started since the 2nd visit back...perhaps just coincidental)
If anything, the overall issue seems to occur less frequently, but the inability to unlock the boot sometimes is a bigger problem. They suggested the next step would be to look at the computer controling the locks.


Skoda Australia are willing to inspect and possibly help me with a warranty claim despite it being nearly 1 year out of warranty. Just wondering if anyone can shed some light on this before I go down that path.

Sounds to me like it is either not properly adjusted to let the locking mechanism close properly, or most likely, you have a fault in the wiring loom. Slamming the door or going over a bump either causes bare or soirted wiring to move, intermittent plugged contact in a faulty or not properly seated plug. One would think the dealer would have already tested the wiring loom, given the symptoms you outline; but then just changing components has been the way of hit & miss tech servicing since valves were first invented. Maybe your dealer's electrician descends from a long line of valve jockeys.
